Introduction

EDR (Ethio-Djibouti railway share company)

Railway share company owned by Ethiopian and Djiboutiangovernment

Established on December 2017 for operation andmaintenance of railway line from Addis to Djibouti.

Currently under management contract with Chinesecompany for the operation and maintenance of the line.

Operation and maintenance is conducted by Chinesestandard usually known as Chinese Class II Standard.

STANDARDIZATION

• According to UIC guideline to standardization document,standards are defined as

“document, established by consensus and approved by arecognized body, that provides, for common and repeateduse, rule, guidelines or characteristics for activities or theirresults, aimed at the achievement of the optimum degreeof order in a given context”.

• Global practice

• ISO (International Organization for Standardization)

• IEC (International Electro technical Commission)

• UIC

International Standards

• The European Committee for Standardization (CEN) and

• The European Committee for Electro technical Standardization (CENELEC)

• France NF

National Standards

Standardization cont.

• African railway standard• So far Africa doesn’t have any significant union of

railways, however some railway lines operate crosscountry like, Sitarail, Tazara and EDR.

• African Union (AU) planned to construct railway linelinking African's major countries with AHSRN Vision2063.

• For that plan to be realized Africa needs one regionalrailway design, construction and operation standard.

List of standards for all disciplines of the Addis Ababa-Djibouti Railway:

safety

Standardization cont.

• Generally Ethiopian government is developing national design,construction , operation and maintenance standard in collaborationwith Ethiopian standardization agency (EQSA).

• During Construction period, some efforts have been made todevelop Railway standardization in consultation with the RussianSaint Petersburg Transport University (PGUPS).

• EDR as a cross country railway operator is planning to developregional standard for the maintenance and operation of its railwayline.

• This can also be done in collaboration and with the support fromUIC.

Technical and financial challenges

The two major challenges in railway industry are:-

1. Technical human capital

2. Financial resource

11/25/2020 11

Technical challenge

• To overcome the technical challenges EDR develops acapacity building model that will enable each keyposition in railway operation to be taken over with inthe shortest possible time.

• The capacity building model is the key element of ourmanagement contract with the Chinese company

11/25/2020 12

Financial challenge

• Basically the financial source of railway construction and operation are

11/25/2020 13

Loan

Private fund

Governmental budget

Joint gov’taland private

fund Financial source

Financial cont.

• Its known that railway line construction is highly capitalintensive and for a continent like Africa it has been amajor challenge for expanding railway infrastructurebecause of financial constraint.

• The major financial source for African railway lineconstruction is loan based.

• Looking at Ethiopian scenario and EDR all the financialsources are from different global loans and Grants sometimes.

11/25/2020 14

• For the construction and operation of cross country railwayline Africa should develop its own regional design,construction, operation and maintenance railway standardsfor a safe and effective implementation.

• Regarding technical human capital, all African countriesshould engage in capacity building programs specifically forrailway sector.

• With an effort of Railway Digitization by UIC, appliedstandards of continental Europe can easily be customizedand disseminated to African Railways.

Conclusion cont.

• And finally regarding financial issue AfricanDevelopment Bank (ADB) should invest in railwaysector for the development of railway infrastructureacross the continent.
